Hello, I`ve got a problem with the link who customers received from my online shop. I`ve tested to purchased some produkt and received mail. On the link to see my bought product I`ve saw an error:
1054 Unknown column 'Array' in 'where clause' SQL=SELECT category_id FROM #__hikashop_product_category WHERE product_id = Array;
What I can do?

I made it. Everything is ok.
